Answer to Question #50456 in Biology for Abe

Question

What is the genotypic ratio and phenotypic ratio of MmNnOoPPQQRrssTtQq?

Answer 1

If two individuals with such genotypes are crossed, the number of different genotypes and thus, phenotypes would be enormous. It is not possible to provide the ratio because it requires writing down hundreds of different combinations of alleles. However, if you ment what will be the number of different genotypes and phenotypes, it can be answered. The number of different genotypes is 3^6 because there are 6 heterozygous locuses. 3^6 = 729. The number of different phenotypes is 2^6 = 64.
